█NOTICE IN USE AND STORAGE

1, Please do not apply D.C.voltage for ultrasonic sensors to avoid migration.

2, Because the sensors have potential direction, please pay attention to its installation location.

3,To ensure reliability and long service life, do not use the sensors where temperature is higher than rated.

4, Can not use the sensors in a vacuum zone or hazardous areas.

5, Do not use in a steam zone, this area of the atmosphere produce uneven temperature gradient will lead to measurement error.

6, The products should not be used or stored in a corrosive atmosphere, especially where chloride gas, sulfide gas, acid, alkali, salt or the like are present. Store the products in the room where is normal temperature and humidity, and avoid the sunlight, sudden changes in temperature and humidity. It may cause of failure or malfunction in such conditions.

7, If you will apply to non-standard frequency and other special conditions, please inform us the specific work conditions, the circuit you need, in order to make sensors to meet your specific requirements.
